Hi,
I am looking at NMEA 2000 compatible GPS antennas.
I would favor the Garmin GPS 19x NMEA 2000 as it has 32 channels and a 10 Hz update rate but from my reading is unlikely to be configurable by the user unless one has a Garmin MFD.
I see in the Installation guide for the Furuno GP330B NMEA2000 GPS Receiver that the Furuno GP330B is mechanically and electrically identical to the Airmar G2183. The Airmar reports GPS position at a user select-able 1 - 10 Hz whereas the more expensive Furuno is spec'd at only 1 Hz. (Note: I am not going to be using it as a heading sensor, just position, but still, this seems a little inferior.)
Is this difference in refresh rate significant for a vessel that cruises at 8 - 12 knots (max speed 17 knots)? Would I be able to see any difference?
Should the Furuno unit not be adjustable to 10 Hz output if it's indeed identical to the Airmar?
I'm interested in maximizing compatibility and avoiding conflicts with my Furuno TZT2, so would favor the Furuno but hate to pay more to get less...
Insights appreciated.
